The worlds first plug and play power steering controller.

The Hang Tight PSC is the world first power steering controller that controls Volvo, Mazda, Dodge and Toyota electric power steering systems without reprogramming.

As seen in builds by

Multi-column

100% Plug and Play. No programming required.

The PSC is the worlds first fully plug and play OEM power steering controller. Hook up power, ground and optional control input (potentiometer, ECU/PWM), and you're ready to drive.

IP68 RATED, FULLY POTTED, DURABLE WATERPROOF DESIGN.

Racing in the rain? Hitting the lake? Don't worry about it. The PSC is built to be water resistant, potted for extra protection.

Control with Potentiometer and ECU control

Banging off the limiter while drifting? Rock crawling up a steep climb in your 4x4? Control the hydraulic output of your power steering pump with optional potentiometer or your engine management system of choice.

Developing the PSC

With Tyson's background in the Formula Drift scene as a trusted builder of wiring harnesses for many pro drift teams, and Terence's love for road course and autocross racing, the constant abuse on mechanical power steering pumps was impacting our ability to build reliable steering systems for ourselves and our customers. This started a years long journey in building the most reliable microcontroller for Dodge, Mazda and Volvo mechanical electrical power steering pumps and Toyota Prius Electric Power Steering Column.

It's like Hyperdrive for your power steering. It made my LS swapped Porsche drive like it's supposed to.

When choosing a connector, keep in mind that crimp quality can impact performance of the controller and pump. If you're not confident in your ability to crimp, or don't have the correct tools, we highly suggest choosing the flying lead option. Our harnesses are professionally built and guaranteed.

Do you need a potentiometer?

Do you need a hydraulic fitting?

The worlds first truly plug and play electric power steering controller, utilizing OEM Dodge, Volvo, Toyota and Mazda electric power steering pumps and assist systems. Our controller will provide you reliability in your power steering system, while opening up full control over the level of assist you want, either with input from an ECU through PWM output, or with a simple potentiometer.

Frequently Asked Questions

What pumps does the Hang Tight PSC currently support?
Dodge

Remote reservoir units

  • 2011-13 Dodge Durango, 3.6L V6
  • 2014-15 Dodge Durango, 3.6L V6
  • 2011-13 Jeep Grand Cherokee, 3.6L V6
  • 2018-20 Jeep Wrangler*** Support TBD

Integral reservoir units

  • 2011-15 Dodge Charger, 3.6L V8
  • 2011-15 Dodge Challenger, 3.6L V8
  • 2011-18 Chrysler 300, 3.6L V8
Mazda

2 connector pumps, integral reservoir. Medium strength pump. Great for classic conversions and lighter drift cars.

  • 2010-13 Mazda 3
  • 2010-13 Mazda 5
Toyota Electric Power Steering Column

Yaris, Corolla and Pruis all use them, making them a very common column unit. Great for classic conversions, lighter track cars or autoX cars that have short lap times. Will create heat during prolonged track use.

There is a shunt resistor that will turn off the unit when the temperature gets too high from the current draw. This can be bypassed for extreme uses, but user beware.

  • 2004-09 Prius/Corolla/Yaris - White connector
  • 2010-15 Prius/Corolla/Yaris - Black connector
Volvo

These pumps are medium strength, similar to Mazda. They can operate in limp mode without the CAN connected, but using a PSC you can control them same as the other units supported.

  • 2004-13 S30, S60
  • 2011-13 S60, C30, C70, V50, XC60

We're always adding support for more pumps and will keep our customers updated when firmware updates are available.

What is the peak amperage draw of an electric power steering pump?

Typically EPAS systems draw 30-40 amps after startup, and can draw as much as 100 amps on startup. It's important to have a stout electrical system in place before installing an EPAS system. The PSC micro-controller draws less than 1 amp.

If you're building your own harness, it's recommended to run minimum 8awg wire for both the ground and power with an 80 amp fuse.

Our kits come with the correct wiring for the application, and need to be ran directly to battery, or to a source with a direct connection to battery.

How do I control the output of the PSC?

You can control the PSC with an optional potentiometer (available through Hang Tight), or using your own PDM/ECU combination. Controlling with a potentiometer is a nice option to quickly adjust the amount of assist in your steering. Going on a casual Sunday street drive? No problem, turn up the assist for easy driving.

Do you make a flying lead/pigtail for my application?

Yes - assembled in Canada by our in-house team, and only made with the best sourced connectors, wire and terminations.

What types of builds does the PSC work well in?

In our opinion, every build type is better with electric hydraulic or assisted power steering. With electric power steering, you have the ability to adjust assist on the go, or have it programmed via your ECU based on whatever input you'd like (RPM, Wheel Speed etc). Modern OEM technology in steering has come a long way in the past 15 years, and with our controller, you can take advantage of it in your Sunday cruiser hot rod, or in the most demanding race conditions.
